Application led June 18, 1924.

To all whom t may concern.'

Be it known that I, HUGO E. Boren, a citizen of the Republic of Germany, residing at Kenosha, in the county of Kenoshal and .St-ate of lVisconsin, have invented new and useful Improvements in Combined lVindow Safety Locks, of which the following is a specification. n

The important object is the provision, in a window construction in which the sashes therefor have one of their edges hingedly secured to strips that are slidably arranged between the bead of a. window casing, and their opposite edges also contactable with strips slidable between the other beads of the window casing, of .key actuated locking means between the sashes and the last mentioned strips for permitting the sashes to be sustained partly opened or wholly closed, and for locking the sashes to the casing against movement in either direction.

To the attainment ,of the foregoing refer- .ence is to be had to thel drawings which accompany and which form part of this application.

In the drawings Figure 1 is a front elevation of the improvement.

Figure 2 is an exaggerated transverse sectional View taken in a line with the locking means for both the upper and lower sashes.

Figure 3 is an enlarged sectional view on the line 3 8 of Figure 1.

Figure l is an edge view of one of the sashes showing the plates secured thereon.

Figure 5 is a plan view of one of the apertured plates secured to the window casing.

Figure 6 is a similar view of the apertured plate secured on one stile of each of the window sashes.

Figure 7 is a sectional view through the locking means approximately on the line 7-7 of Figure 8.

Figure 8 is a sectional view on the line 8'-8 of Figure 7 Figure 9 is a fragmentary sectional view of the construction disclosed in Figure 7 but showing the bolt moved to its full position in one direction, and to its full position in an opposite direction by dotted lines.

Figure 10 is a perspective view of the spring employed.

Figure 11 is a similar view of the catch member employed.

The window casing 1 is of the ordinary COMBINED WINDOW SAFETY LOCK.

construction, the same beingprovided with inner stop beads 2, outer stop beads 3 and parting beads el arranged between the stop beads.

Between the beads a pair of lower strips 5 and 6 respectively and a pair ot' upper strips 7 and 8 respectively. Both pairs of .strips have attached thereto the usual cords that are trained over pulleys attached to weights in the boxes of the casing. The lower strips 5 and 6 may be and preferably are of a less width than the upper strips 7 and 8, this being especially true with respect to thc lower strip To the strips 5 and 7 there are hinged the lower stile 9 and the upper stile l0 respectively. The opposite stiles of the sashes 9 and 10 are channeled longitudinally on their outer faces, as indicated by the numeral 11 in Figure 3 of the drawings to provide Shoulders 12 which are designed to abut with like shoulders on the strips 6 and 8. Preferably the ends of the strips 6 and 8 projecting beyond their shoulders are beveled, as at 13 and the channeled portions 11 of the stiles of the shafts E) and 10 are likewise beveled.

Secured to the inner face of the strips 5, 6, 7 and 8 there are plates 14. Any desired number of these plates may be employed on each strip. The confronting faces of the stop strips 2 and 3 and the parting strips 4 are grooved longitudinally as most clearly disclosed in Figures 2 and 3 of the drawings, and the projecting ends of the plates 14 are received in these grooves.

On the inner walls provided by the grooves between the stop and parting strips, and in a line with and extending in opposite directions from the center of these strips there are secured upper and lower plates 15 respectively. These plates are provided with round openings 16 that align with sockets 17 in the side of the casing.

Let in the outer face at the center of the strips 6 and 8 there are metal casings, each of a similar construction and each indicated by the numeral 18. Each of the casings 18 is preferably of a. substantially elongated rectangular formation and has arranged for slidable movement therethrough a bolt member 19. The bolt is movable through the openings 16 in the plates 15 and into the sockets 17 and is likewise movable into sockets 20 in the stiles of the sashes adjacent thereto. To protect the sockets gouter reduced end with a substantial tangular socket 2G for the reception of a there is secured on the inner faces of the said stiles metal plates 21 each of which being provided with a bolt opening 22.

Each bolt 19 has its under face at the center thereof formed with a series of teeth 23 engageable by teeth 24 on approximately one-half of a roller 25 that has its ends reduced and journaled in bearings on the inner and outer faces of the casings 18. Each of the members 25 is centrally formed, on its ly recsimilarly shaped key, whereby to turn the members 25 and likewise move the bolts 19 longitudinally.

The bolts 19 have their upper edges notched at desired spaced intervals, as indicated by the numeral 27, the side walls provided by these notches are preferably arranged at outward angles.

In each of the casings there is a substantially U-shaped member indicated by the numeral 28 that has its ends directed toward the bolt. The ends are centrally formed with tongues 29, the said tongues being disposed centrally in upwardly curved openings 30. The body of the bolts are ref ceived in the openings 30 and the tongues 29 are designed to engage with two of the notches in the bolt. The member 28 Vis influenced to bolt engagement by an arched spring 31 centrally contacting with the top or with a plate 32 in the casing.

The U-shaped members 28 are in the nature of spring influenced tumblers and by reference to Figures 7 and 9 of the drawings it will be noted that the bolt V19 has an equal number of notches therein. lThe tonv gues 29 of the tumbler member 28, in the position illustrated in Figure 7 engage in the notches adjacent to the end notches in the bolt, and when in this position the bolt locks the stiles of the sashes 9 and 10 to the strips 6 and 8, and likewise locks the said strips @and 8 to the casing, thus preventing the sliding of the sashes. When the bolt is moved to the position illustrated by the full lines in Figure 9 the stiles 6 and 8 will be locked to the sashes and 10,

which permits the free sliding of the sashes.L

When the toothed member 25 is turned to move the bolt to the dotted line position illustrated in Figure 9, 'the strips 6 and 8 are locked to the frame and release the sashes therefrom, permitting the said sashes to be swung to open position on their hinge connection with the strips 5 and 7.

Having described the t invention, I claim A locking means for the purpose set forth, comprising a casing, a bolt which is round in cross section slidable through the casing, said bolt having its upper edge formed with equi-distantly spaced notches, and its opposite edge at. the center thereof provided with teeth, a roller having its ends journaled VVin the sides of the casing and provided with teeth for engagement with the teeth of the bolt, aremovable operating element for the roller, a substantially U-shaped member in the casing having the ends of its parallel arms rounded inwardly to straddle the bolt and its said rounded portions centrally formed with tongues to engage the notches ofthe bolt, and an arched spring supported in the casing and having its ends contacting with the corners of the. 'U-shaped member to influence the arms thereof into bolt engagement.

In testimony whereof I affix my signature.
